Hi community!

I had askbot running for months, but now I started getting 500 internal error. I'm stuck with the issues for days now. Please suggest if I'm missing anything (In case you recommend a re-installation, could you point me to some link which helps reinstalling askbot - keeping all my data/settings intact)

The full track-back is here,

One important line in the trace is this one,

[Wed Jul 11 16:04:07 2012] [error] [client 127.0.0.1] File "/home/probaho/lib/python2.6/askbot-0.7.36-py2.6.egg/askbot/templatetags/extra_tags.py", line 142, in render

Those lines read this,

   136  class IncludeJinja(template.Node):
   137      """http://www.mellowmorning.com/2010/08/24/"""
   138      def __init__(self, filename, request_var):
   139          self.filename = filename
   140          self.request_var = template.Variable(request_var)
   141      def render(self, context):
   142          request = self.request_var.resolve(context)
   143          jinja_template = get_template(self.filename, request)
   144          return jinja_template.render(context)
